REGISTER FOR POOL-TRIANGLES.

SPECIFICATION forming part of Letters Patent No. 551,089, dated December10, 1895.

Application filed April 6, 1895,

To all whom it may concern.-

Be it known that we, JULIUs DE NEER- GAARD, a citizen of the UnitedStates, and SorHUs J. E. WILIIJELM, a subject of the King of Denmark,residents of Brooklyn, in the county of Kings and State of New York,have invented a new and useful Improvement in Registers, of which thefollowing is a specification.

The object of our invention is to provide a register adapted for use inrooms used for games pertaining to billiards, and more particularly forgames of pool, in which a frame or triangle is used to collect the ballsand adjust them in position on a table for a new game.

By our invention the proprietor will be informed as to the number ofgames to be settled for at the end of a series and also what the cashreturns should be during the day.'

In the accompanying drawings, Figure 1 is a front view of a registerconstructed according to our invention. Fig. 2 is an enlarged front viewof a portion thereof with some of the parts removed. Fig. 3 is asectional side view thereof, and Fig. 4: is a detail of certain parts.

a designates a casing, which may be of any suitable design and material.As here shown, it has a circular upper portion to inclose the operatingmechanism of the register, which is covered by a dial-plate a and by ahinged cover (F, the latter capable of being locked to the casing andhaving its central portion formed of glass. The lower portion of thecasing may conform approximately in shape to that of an ordinarytriangle and is provided with a receptacle a for holding the latter whennot in use. This receptacle comprises a back portion having bottom andside walls or strips to guide and support the triangle in place. Theupper portion of the receptacle a is inclosed by the cover a and also bya strip a, secured to the casing and extending downwardly a suitabledistance.

Z) is a push-bar fitted to slide between parallel side walls arranged atthe uppermost end of the receptacle. This bar is secured to a stemb,passing through the top wall of the receptacle and pivotally connectedto the free end of a lever 0.

Serial No. 544,750. (No model.)

In order to replace the triangle in its receptacle, it is necessary toinsert one of its corners beneath the strip a and then raise thetriangle sufficiently for its bottom side to pass over the bottom Wallof the receptacle. In doing this the push-bar I) will be forcedupwardly, causing the lever c to be rocked. The lever o is affixed tothe spindle (Z of an ordinary alarm device 6, comprising a gearwheel 6,loosely mounted on the spindle (Z and engaging in a pinion 6 secured toa shaft 6 f is an escapement device provided with a hammer to act on abell f.

g is a ratchet-wheel secured to the spindle (Z and arranged to impartmotion to the wheel 6 during the downward movement of the push'bar b.

h is a coil-spring, which is wound up during the upward movement of thepush-bar Z) and aids to lower the latter and operate the registermechanism each time a triangle is withdrawn from the receptacle.

Z is a wheel provided with a suitable number of preferablyratchet-shaped teeth around its periphery. It is secured to a shaft Z,working in a bearing Z and in a bridgepiece Z secured to the casing.This shaft extends through the dial-plate a, whose dial corresponds innumber of divisions to the number of teeth around the wheel Z.

m is a pointer fitted to a squared portion of the shaft Z, in order totravel continuously therewith and register the total number of gamesplayed during the day or other period of time.

m is a pointer secured, friction-tight, on a cylindrical portion of theshaft Z, in order that it may be set back by the proprietor to zero atthe end of a series of games played by different parties.

The wheel Z is rotated by means of a finger n in the form of a resilientstrip of thin material, rigidly secured at one end to the hub of thelever c. The extremity of the free end of this finger is provided with alip or flange n, and is inclined in cross-section in order that itsfront edge may occupy a plane slightly beyond the outer side of theWheel Z and its rear edge occupy a plane slightly beyond the inner sidethereof. When the finger is rocked upwardly along with the lever 0, itsrear edge will, by reason of the inclined end and resiliency of thefinger, pass freely over the front of a tooth of the wheel and be sprungin between it and its adjacent tooth, as shown in Fig. 2. The downwardmovement of the finger will, by means of the lip n, rotate the wheel adistance equal to the pitch of the teeth and then pass out of engagementtherewith, as shown dotted in Fig. 2. An arm 0 of the lever 0 may bearranged to sustain the front edge and bottom side of the finger whenoperating to rotate the wheel, as shown in Fig. 4.

q is a pointer to indicate the number of revolutions of the pointer mand multiply the numbering capacity of the register. Its spindle isjournaled in a frame q, secured to the casing, and is provided with atoothed wheel g containing teeth corresponding in number to that of thedivisions of the index of the pointer q. Motion is imparted to the wheelg to the extent of the pitch of its teeth by a pin (1 secured to thewheel Z.

19 p are resilient detents respectively e11- gaging the teeth of thewheels Z and g to lock them in correct position after each movementthereof.

The wheel Z and the finger n coactingtherewith may be arranged in anyposition, and if desired the finger may be fulcrumed between its endsand the push-rod and finger arranged on opposite sides thereof. In thiscase the register-pointer will operate during the in sertion of thetriangle instead of its withdrawal.

Our improvement is applicable to a number of uses, and we do not confineourselves to the precise form of construction shown. The alarm mechanismmay also be dispensed with, if desired.

We claim- 1. In combination with the casing of the register, of atriangle receptacle secured thereto, and arranged beneath the same, andcomprising a back portion having bottom and converging side walls, itsapex having a push piece fitted to slide therein to operate the registerby means of the triangle, substantially as described.

2. In a register,the combination of a toothed wheel, a detent to holdthe same in correct positions and a resilient pawl or finger mounted ona stationary pivot for rotating the wheel, the pawl being in the form ofa flat thin strip of resilient metal, provided with a projecting lip atits extremity, and having its free end inclined to the transverse planeof the teeth of the wheel, to be sprung sidewise to pass the samewithout engaging them when rocked in one direction, and to engage androtate the wheel the distance of a tooth when rocked in a reversedirection, substantially as described.

3. In a register, the combination of a casing containing a receptaclefor a triangle, having its upper portion inclosed, a toothed wheeloperating a dial pointer, a resilient detent to hold the wheel incorrect positions, a supplementary pointer having its actuating toothwheel rotated the space of atooth by the main pointer wheel eachrevolution thereof and locked in position by a resilient detent, alarmmechanism to sound at each movement of the pointer, a lever mounted onthe spindle of the alarm mechanism and pivotally connected to the stemof a push bar within the receptacle, and a resilient finger secured torock with the lever, the said finger having a free end portion, inclinedto pass the teeth of the wheel freely when rocked upwardly andcontaining a lip to engage and rotate the wheel when rocked downwardly,and to pass out of engagement therewith, substantially as described.

In testimony that we claim the foregoing as our invention we have signedour names, in presence of two witnesses, this 30th day of March, 1895.
